I found an old save dated 12/23/15 that I had started with a new household consisting of a single dad and his young son. I had moved them into the Daisy Hovel lot and then left them there and forgot about the game.
The first thing I did was downsize the house to a Micro Tiny Home. I kept most of the items that came with the house to furnish their tiny home. I sold the double bed and bought two twin beds. I had enough money left over to buy one toy for the kid and a guitar for the dad. Dad has The Curator aspiration and his traits are active, materialistic, and music lover. The kid has the Rambunctious Scamp aspiration and his trait is Loves Outdoors. Their save started on Sunday morning at 8:00 AM.
After playing them for one hour:
1. I like the sentiments. The little boy is protective of his dad and they adore each other.
2. I like that the little boy can help with the finances by looking for frogs, digging rocks, and fishing. He found a lot of crystals, several frogs, and some metals that went into dad's inventory since he has The Curator aspiration. The little boy caught an orchid while fishing in the pond at the Oasis Springs park which dad planted right away. It looks like money won't be an issue for them much longer. Fortunately, it's a slow-growing plant so they won't get rich too fast.
3. The social buff from living in a Micro Tiny home is very strong. I knew the little boy was going to be a Spellcaster someday so I had him introduce himself Morgyn Ember and L. Faba who were walking around their neighborhood after they got home from the park. They both became instant Good Friends and followed him home where they met dad and became Good Friends with him too. They also met Caleb and Vlad who were wandering around the neighborhood that evening. By 9:30 PM on Day 1 of their save, dad and his son both had 5 Good Friends, not counting each other - they had also met an Alien.
I've played this household through Thursday night of the first week. The little boy has maxed the motor skill, caught a dragon fruit fishing at Magnolia Promenade. Dad caught Volume 1 of the Vampire Encyclopedia. I think the game is hinting that dad might become a Vampire. Dad has almost maxed fitness, is working on rock climbing, and has completed several odd jobs.
I wish that I had looked at the child aspiration rewards sooner. When I did that I lost interest in having the kid complete any of them because skilling is already easy. I'd like for him to have something left to do when he grows up.
What I've found while playing this household:
1. Making friends is too easy.
2. Gaining money is too easy.
3. Leveling skills is too easy.
4. The Active trait is over-powering at times. I needed to have the kid play on a jungle gym while in a playful mood. This meant that I had to get him to take a bubble bath before going to the park where dad would immediately "fire him up" because he has the active trait and can do that. Boom - the kid lost his playful mood and became energized. So dad had to start staying home. By this time the little boy had entered a clingy phase so whenever he headed to the park he started to get tense about not being with his dad (which even made me sad). It also made his dad sad.
5. I still don't like 98% of the pre-made Sims that come with the Base Game, City Living, Get Together, and Island Living.
Sentiments really are a very nice addition.
Game-play wise I had no lag, no crashing, and no last exceptions.
